sure, but it would be even easier if I didn't have to write that code 
myself (last time I did that, I needed a couple of tries before the 
parser handled all cases correctly...).

but maybe this could simply be handled by a helper generator in the 
tokenizer module, that simply wraps the standard tokenizer generator
and inserts whitespace tokens where necessary?

you'll still have to deal with multiline strings, right?
